I use NFS share in my local home network. NFS mount is defined in /etc/fstab as following:
192.168.1.1:/media/Share /media/Share nfs noauto,rw,hard,intr,tcp,rsize=32768,wsize=32768,users 0 0
When I suspend my laptop with NFS share mounted (mount was done via clicking on the share name in nautilus), then bring the laptop to my work place (where of course my NFS share is no longer available), resume it from suspend, enter password - it hangs there.
The only workaround I found is switch to VT3 (using ctrl+alt+f3), login there, unmount forcibly /media/Share, then switch back to VT2 and the graphical login will succeed.
Is this a bug? I used the same NFS mount on Ubuntu 17.10 and it had no issue with that.
